Improvement in stop-cock casings



UNITED STATES PATENT PATRICK BURKE, 0F ROCHESTER, NEWORK.

'IMPROVE-[VIENT IN STOP-COCK CASING'S.

Specification forming part of Letters Patent No. 207,246, dated August 20,1878; application filed A May 13, 1878.

to be a `clear and accurate description'thereof,

ing, in whichy vIiigure 1 is a vertical central v section of my invention, showing it in position, with the reference being had to the accompauyin drawusual accompaniments. Fig. 2"is a plan vichy4 of the cap and cover; and Figs. 3, 4, 5, and 6' show details and modifications.

The object of my invention. is to produce' a convenient and durable casing for the stopl cocksnd 4operatingrods ,pertainingtn .subs terra'nean pipes for' 'conveying steam, water, gas, or other fluids; and .it consists, mainly7 in' a peculiarformbf the'lwer casing, in connection with an adjustable upper section, and

a compoundcap for cover surm ountin g the latf4 ter. A Ais the main or stationary part of the casing, which for 'convenience has an enlarge-- ment, B, at itsV base Jto-receive the stop-cock E in the pipeF. r.'.lhe portion A of this lower vcasing is preferably made square in cross-section, as shown in Fig. 3 5 but it" may be made polygonal or elliptical, asin Fig. 4, or any other desirable shape not round and it is sur-y4 mounted by a contracted neck, through the center of which the adjustable upper section, C, of the casin g passes, moving freely therein. D isa flangeahich is firmly secured to the upper end oli-the section C, and rests upon the earth or pavement at or slightly beneath the surface thereof. Y :M *w

Thus it will be observed that the casing can be adjusted to pipes laid at different depths by sliding -the upper section in or out, as the case may be, and., that, after setting, the casng'is self-adjusting to variations in the soil or pavement. i

A nut or block, b, is rigidly attached to the lower end of pipe C, and is fitted to slide easily in the part A of fthe lower casing; and itis obvious that, on account of the non-circa lar contour of the latter, the pipe C is prei vented vfrom revolving during the operation of attaching or removingthe cap D, or any portion of it. By mea-us, also, of the neck d and block b, the upper section, C, :is retainedin fsonie operation, as the 4threads became rusty by exposure to the moist earth, and, moreover,

`when the soil was loosearound the casing,- as

is often the case, the adjustable section would drop down.

V I obviate ,hotnthese difficulties. byma- -nently attaching the'flauge 1) to the pipeU,

' thus dispense with the enlargement B; but by the use of the latter an unnecessary weight of metal in the body of the casing is avoided. By means of slots in the sides of the casing at B the latter may be removed or replaced without disturbing the pipe F or stopco'ck, and I nd it desirable to provide flanges upon the base to prevent settling. The turn-rod e is attached to the stop-cock in the usualman- Aner, and it may be retained in a central position by a collar, c.

It is plain that the arrangement of the ad justable section C within the portion'A may be reversed, and the latter be formed to slide into the former," the` o1'i`eration'being substantially as above described, f-in fwhich case the block b would lbe attached to the section A and the neck d to the" section C.

I am aware that stop-cock casings with ad* ,instable upper sections arenot new, such cas FFIGE.'

j'ustaLbe section C, in combination with a lower easing,`A, of non-circular cross-section, operating substantially as described.

3. The easing A, provided with the neck d, in combination with th'eblock b and adjustable seetion C, whereby the latter is retained in a Vertical y )sition7 substantially as set forth.

P. BURKE.
